... Hardware method that disables any combination of sectors from write or erase operations GENERAL DESCRIPTION The Am29F040 Mbit, 5.0 Volt-only Flash memory organized as 512 Kbytes of 8 bits each. The Am29F040 is offered in a 32-pin package. This device is designed to be programmed in-system with the standard system 5 ...
Page 2
... This device also features a sector erase architecture. The sector mode allows for 64K byte blocks of memory to be erased and reprogrammed without affecting other blocks. The Am29F040 is erased when shipped from the factory. The device features single 5.0 V power supply opera- tion for both read and write functions. Internally gener- ated and regulated voltages are provided for the program and erase operations ...

... All addresses are don’t cares except A0, A1, and A6. The manufacturer and device codes may also be read via the command register, for instances when the Am29F040 is erased or programmed in a system with- out access to high voltage on the A9 pin. The command sequence is illustrated in Table 4 (refer to Autoselect Command section) ...

... Low V Write Inhibit CC To avoid initiation of a write cycle during V and power-down, the Am29F040 locks out write cycles for V < V (see DC Characteristics section for CC LKO voltages). When V < the command register is CC LKO disabled, all internal program/erase circuits are disabled, and the device resets to the read mode. The ...
